Na3La2(BO3)3的晶体结构
Crystal Structure of Sodium Lanthanum Borate Na3La2(BO3)3
摘要
Abstract
Single crystal of Na3La2(BO3)3 was grown from the high temperature solution by employing Na2CO3-H3BO3-NaF as fluxes. The structure was established by single-crystal X-ray diffraction method. The compound crystallizes in the orthorhombic system, space group Amm2 (No.38) with a=0.51580(10) nm, b=1.1350(2) nm, c=0.73230(15) nm, α=β=γ=90°, V=0.42871(15) nm, and Z=2. Its three-dimensional network structure is formed by isolated BO3 triangles held together by the Na(1)O6, Na(2)O8, Na(3)O6, and La(1)O9 polyhedra. The relationship between the structure and optical second harmonic generation (SHG) effect of Na3La2(BO3)3 crystal was also discussed.关键词
